The goal of education for all is now being looked into freshly by the organizations concerned to ensure that not just education but quality education is received. In Kenya, it is a ministerial requirement that public organizations including educational institutions develop strategic plans as a means of enhancing results-based management and efficiency in their operations. Even the schools with strategic plans rarely implement them and the result has been haphazard planning techniques, poor prioritization, and failure to use the meagre resources for the right projects. A descriptive design was used in this study. Descriptive and inferential were used to analyse the qualitative data obtained to enable critiques to conceptualize the results. The study established that in summary, there was a positive and significant relationship between communication and the implementation of the strategic plan in public secondary schools at r=. 445**, p<. 01 significant level contributing 19.8% variability to the implementation of strategic plan when other factors are held constant. The study established that there was a positive and significant relationship between leadership activities and the implementation of the strategic plan in public secondary schools at r=. 667**, p<. 01 significant level contributing 44.5% variability to the implementation of a strategic plan when other factors are held constant. Lastly; the study found that there was a positive and significant relationship between Resources and the implementation of the strategic plan in public secondary schools at r=. 767**, p<. 01 significant level contributing 58.8% variability to the implementation of strategic plan when other factors are held constant.
